# This is a wrapper script to run a dist gem5 simulations.
|

# See the usage_func() below for hints on how to use it. Also,
|
||||
# there are some examples in the util/dist directory (e.g.
|
||||
# see util/dist/test-2nodes-AArch64.sh)
|
||||
#
|
||||
#
|
||||
# Allocated hosts/cores are assumed to be listed in the LSB_MCPU_HOSTS
|
||||
# environment variable (which is what LSF does by default).
|
||||
# E.g. LSB_MCPU_HOSTS=\"hname1 2 hname2 4\" means we have altogether 6 slots
|
||||
# allocated to launch the gem5 processes, 2 of them are on host hname1
|
||||
# and 4 of them are on host hname2.
|
||||
# If LSB_MCPU_HOSTS environment variable is not defined then we launch all
|
||||
# processes on the localhost.
|
||||
#
|
||||
# Each gem5 process are passed in a unique rank ID [0..N-1] via the kernel
|
||||
# boot params. The total number of gem5 processes is also passed in.
|
||||
# These values can be used in the boot script to configure the MAC/IP
|
||||
# addresses - among other things (see util/dist/bootscript.rcS).
|
||||
#
|
||||
# Each gem5 process will create an m5out.$GEM5_RANK directory for
|
||||
# the usual output files. Furthermore, there will be a separate log file
|
||||
# for each ssh session (we use ssh to start gem5 processes) and one for
|
||||
# the server. These are called log.$GEM5_RANK and log.switch.
